Re: swapping the router

Changing the router does not affect the modem connection nor the Openreach DLM. There is no problem doing it. You do not need to power cycle the modem.

I would still not change the router, (or reboot it), a lot within a short period. The BTW DLM still performs some functions, though apart from the IP Profile setting I don't know what. Just prudence .

How I wish your first statement could be 100% true. I have four 2wire 2701 routers all with the same firmware build and I have even checked the releases of the component modules. There are two hardware builds - 008 and 009. -008 gives a great stable throughput but the -009s are all over the place! and caused the line profile to be reduced.

Re: swapping the router

Ummm. A good point, but in essence you are talking about faulty kit. Not what I believe the OP was asking, but a valid concern perhaps. In my opinion it's less likely to be an issue than the same thing happening on ADSLx.

You also seem to be saying that the chaos caused the sync to drop? That's interesting, as we don't know how that could be caused other than by the BTW DLM telling the OR one that it wasn't happy. The OR DLM is, so far as I'm aware, nothing to do with session control. Any contrary information or ideas?

Re: swapping the router

You might think it is faulty - but it does not appear so ... I have tried quite a few of each build on the line with the same results and they can work perfectly on other line. Currently with 2wire for investigation but they are scratching their heads too.

Yes, the -009 routers resulted in a lower profile. Put the -008 back on, wait for a while and it would be back up! BT moved it from Tech Support to Second line and then to the development team before putting the issues to 2Wire.

I suspect the OP was talking about FTTC and not ADSL, but his post wasn't clear
